Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for adhering powder such as mica powder and talc powder to a running cable core in a manufacturing process of electric cables and the like.

[Conventional technology]

When extrusion-coating a conventional cable, a mica or talc is used as a release agent in order to prevent sticking between the cable core and the coating layer or between the coating layers in the two-layer coating to facilitate peeling. The extrusion coating is performed after the powder such as the above is attached to the surface of the cable core.

As a conventional device for adhering the powder to the surface of the cable core, a guide roller that rotates at a fixed position is provided in a container containing the powder, and the cable core is guided by the guide roller to run in the powder. Is used.

[Problems to be solved]

In the conventional powder adhering device as described above, the powder adheres to the cable core passing through a certain position and is conveyed, so that another powder is not replenished after that and the cable core running path inside the powder in the container A cavity is created. This sometimes required the person to stir the powder.

Further, since the pressing roller is fixed in the container, it is difficult to carry out the wire passing work if the powder is contained in the container, and it is necessary to take out the powder once and then wire it, which is poor in workability. There was a problem.

The object of this invention is to solve the above-mentioned problems of the prior art by constantly changing the running path of the cable core passing through the powder, and by rocking the container itself, the powder core is evenly distributed in the powder core. It is an object of the present invention to provide a cable core powder adhering device capable of adhering a cable.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention has an arm swinging means for swinging the arm within a predetermined angle range by attaching a pressing roller for running while the cable core is embedded in the powder to one end of the arm. (EN) Provided are a cable core powder adhering device provided with container oscillating means for oscillating a container, and a cable core powder adhering device provided with elevating means for elevating and lowering an arm to which the pressing roller is attached.

[Action]

The device of the present invention has the above-mentioned structure, and its operation will be described below.

First, the lifting roller such as a cylinder is raised to lift the pressing roller out of the powder to pass the cable core through the wire, and then the pressing roller is lowered to lower the pressing roller and the cable into the powder. Embed the core.

After that, the cable core is run, and at the same time the arm is rocked by the arm rocking means, the container itself is also rocked by the container rocking means, and the powder core adheres to the cable core in the cable core running path and is carried. After the powder that has been removed, the powder around it is replenished.

Therefore, a powder cavity is not generated after the cable core running path, and the powder is sufficiently adhered to the cable core.

〔Example〕

In the embodiment shown in the drawings, 1 is a container for filling powder.

Brackets 4 and 5 are provided on columns 2 and 3 provided near both ends of the container 1, and a pair of guide rollers 6 rotating around a vertical axis and a horizontal axis are provided on one bracket 4. A grooved guide roller 7 is provided.

Further, on the other bracket 5, a grooved guide roller 8 that rotates around a horizontal axis and a pair of guide rollers 9 that rotate around a vertical axis are provided.

The container 1 is rocked by the container rocking means 11,
The swinging means 11 has a structure described below.

That is, the bearings 1 provided on the substrate 12 at the four front, rear, left, and right positions
Both ends of an eccentric shaft 16 are fixed to a disk 15 at the inner end of each rotary shaft 14 supported by the respective shafts 3, and a bearing 17 at the bottom of the container 1 is rotatably supported by each eccentric shaft 16.

The rotary shafts 14 are interlocked by a chain transmission device (not shown) so as to rotate in the same direction at the same speed.

A shaft of a geared motor 19 is connected to any of the rotary shafts 14 so that the container 1 is swung by the motor 19.

A vertical guide rail 21 is erected on the substrate 12 at the rear intermediate portion of the container 1, and an elevating table 23 is fixed on an elevating member 22 mounted on the guide rail 21 so as to be able to move up and down.

The elevating table 23 is moved up and down by elevating means 24 such as an air cylinder. A bearing 25 is provided on the table 23, and a shaft 27 at the upper end of an arm 26 is rotatably supported by the bearing 25.

Reference numeral 28 denotes an arm swinging means, which is a reduction gear 3 for reducing the rotation of the geared motor 29 and the shaft of the motor 29 and transmitting the decelerated rotation to the shaft 27.
0, and the arm 26 is swung within a predetermined angle range by rotating the geared motor 29 forward and backward.

If a crank mechanism is used instead of the reduction gear 30, the motor 29 is rotated in a fixed direction.
The arm 26 can also be swung.

A pressing roller 32 having a groove is rotatably attached to the front part of the lower end of the arm 26, and the stirring blade 3 is provided on the front surface of the roller 32.
Fix 3

In addition, 34 is powder such as mica powder filled in the container 1.

Next, the operation of the above embodiment will be described.

First, the elevating means 24 is operated to elevate the elevating table 23 so that the pressing roller 32 escapes from the powder 34 in the container 1 as shown in FIGS.

Next, the desired cable core 35 is passed between the left and right guide rollers 6, guided downward from the upper side of the guide roller 7 to the groove of the pressing roller 32, guided from the lower side to the groove of the pressing roller 32, and guided upward to the groove of the guide roller 8 from the upper side. After that, a wire passing operation for passing between the left and right guide rollers 9 is performed.

After that, the elevating means 24 is actuated to bury the pressing roller 32, the blade 33, the arm 26 and the cable core 35 together in the powder 34 as shown in FIGS.

Next, the cable core 35 is moved in the direction of the arrow, and at the same time, the geared motor 29 is rotated forward and backward at regular intervals to move the arm 26.
Is swung within the range of the chain line shown in FIG.

On the other hand, the geared motor 19 drives each rotating shaft 14 to rotate the eccentric shaft 16 to swing the entire container 1.

In this way, while swinging the container 1 and the arm 26,
By passing the cable core 35, the powder 34 attached to the cable core 35 and carried away is replenished with the powder 34 in the vicinity thereof.

Further, the blades 33 provided on the front surface of the pressing roller 32 rotate together with the roller 32 as the cable core 35 travels to stir the powder 34 in the vicinity, and after the powder 34 that has adhered to the cable core 35 and carried away. To serve as a powder 34 in the vicinity.

With the above operation, the powder 34 can be sufficiently attached to the cable core 35.

[Effect of device]

According to the present invention, the cable core buried in the powder travels while swinging together with the arm by the above-described configuration and operation, so that the cable core always travels while moving in the powder. It is possible to sufficiently attach the powder to the cable core without forming a hollow portion of the above, but in the case of this invention, the effect is further enhanced by rocking the entire container.

Further, since the arm having the presser roller attached thereto can be moved up and down by the ascending / descending means, the presser roller can be ejected above the powder when the cable core is threaded, so that the wire threading work can be performed efficiently. There is.
